Definitions
- the invention relates to a device for producing a homogeneous powder-air mixture having a pressure section and a suction section, wherein the two sections merge into one another in an outlet.
- the invention also relates to a method for producing a homogeneous powder-air mixture.
- EP 0 636 405 A2 discloses an apparatus in which a solid jet is mixed with gas and an intimate mixing of solid and air is attempted with the aid of a coaxially arranged lance. But such devices are very complex in construction and prone to operation.
- the invention is therefore based on the object to provide a device for producing a homogeneous powder-air mixture, which is simple in construction and which ensures the production of a homogeneous mixture.
- the pressure section opens in particular orthogonal in the suction section in the manner of an ejector and the suction section is open to the outside outwards.
- an inhomogeneous powder-air premix is supplied under pressure to the device according to the invention, this mixture, which is supplied at a high flow rate, sucking in air from the suction section and mixing with this aspirated air in the further course.
- the air is drawn in from the environment and does not have to be supplied separately.
- the supply of previously prepared inhomogeneous powder-air mixture which, as already mentioned, has a high flow velocity, via a pressure line, which opens into the pressure section.
- the pressure section In order to supply the inhomogeneous powder-air mixture as evenly as possible with the ambient air, the pressure section is completely surrounded by the suction section. As a result, the powder-air mixture uniformly and uniformly draws in air and therefore can mix evenly with the sucked air.
- the pressure section according to the invention is enveloped by the suction section. In other words, the pressure section opens centrally into the suction section.
- the suction section has a plurality of breakthroughs or suction openings open to the environment. These suction openings extend radially, are arranged radially around the pressure section and open into the environment. In a variant, the suction openings extend at an angle to the radius, whereby the effect is achieved that the sucked air is forced to a twist.
- the suction openings are arranged distributed uniformly over the circumference of the pressure section.
- a uniform mixing of the inhomogeneous powder-air mixture is additionally supported with the sucked ambient air.
- the outlet has a cylindrical shape and is circular.
- this outlet is the homogeneous powder-air mixture, which is supplied to the consumer, for example, a pollination system.
- the outlet is not formed as a diffuser but has a constant cross-sectional size, so that the speed of the homogeneous powder-air mixture over the cross section is uniform.
- An embodiment provides that in the suction section of the outlet of an upstream, an inhomogeneous powder-compressed air mixture producing mixer opens.
- a mixture can be produced, for example, with a device according to DE 199 37 557 A1.
- This mixture has the required flow velocity for the device according to the invention, so that sufficient ambient air can be sucked in via the suction section and this ambient air mixes with the premix by strong turbulence in the suction section and / or in the outlet.
- the object mentioned at the outset is also achieved by a method in which a pressurized inhomogeneous powder-air premix is injected into a suction section and thereby draws in ambient air and forms a homogeneous powder with this ambient air in the suction section and / or in an outlet. Mixed air mixture.
- the ambient air is supplied to the inhomogeneous powder-air premixture orthogonal to its flow direction.
- Figure 1 shows a longitudinal section through a device for
- FIG. 2 shows a section II according to FIG. 1.
- FIG. 1 shows a device, generally designated 10, for producing a homogeneous powder-air mixture which is used, for example, in a dusting device for dusting printed paper sheets on a printing press.
- a device for producing a homogeneous powder-air mixture which is used, for example, in a dusting device for dusting printed paper sheets on a printing press.
- powder is conveyed from a storage container (not shown) via a metering device (not shown).
- This powder falls into a funnel 14, which opens into a suction line 16.
- the reference numeral 18 denotes a pipe connection, via which compressed air is supplied.
- This pipe socket 18 opens into an annular distributor chamber 20, in which the compressed air is passed evenly into an annular space 22. In this annular space 22, the compressed air is deflected around the intake pipe 16 around down, so that a sheath jet is formed.
- the intake pipe 16 opens, so that powder from the hopper 14 and the intake pipe 16 is entrained by the envelope jet.
- This mixture of powder and air has a flow velocity, but is still inhomogeneous and is in a pressure section 24, in which it flows vertically downwards. In this case, it flows through a suction section 26, which radially surrounds the pressure section 24 and which is open radially to the outside via openings 28 (in total 4 openings). This can be clearly seen in FIG. Axial following the suction section 26 there is an outlet 30 which is circular-cylindrical.
- the inhomogeneous powder-air premix flows under pressure into the pressure section 24 and sucks air from the environment into the suction section 26 via the openings 28.
- a conically narrowing section 32 the inhomogeneous powder-air premix and the radially drawn in ambient air mix to a homogeneous powder-air mixture, which is blown through the outlet 30.
- the powder core still present in the pressure section 24, which is surrounded by an enveloping jet of compressed air is dissolved and the powder is homogeneously mixed due to the addition of the radially incident suction air, so that a powder distribution which is homogeneous over the cross section prevails at the outlet of the outlet 30.
- the entire device 10 is made of turned parts and axially plugged together and is axially clamped and held together by means of suitable clamping elements, such as screws or the like.
